In addition to the ability to unlock an alternative campaign with a different story for the PSP title Resistance: Retribution via a special "Infected Mode" unlocked from Resistance 2, players will be able to play Retribution with a Dual Shock 3. By activating the "PSP Plus" feature in Resistance 2 with a PSP playing Resistance: Retribution connected, players can play through a modified version of Retribution tuned for the controller. Aim assist is turned off, the game becomes more challenging, and the rumble function works. Combined with the video out capabilities of the PSP Slim and PSP-3000, this turns Retribution into a pseudo-console game.

While the addition of this "Infected Mode" sounds like a great bonus for Resistance fans, the new PSP Plus feature is strange. Having to hook the PSP up to both the TV and the PS3 is a little awkward, but those without the TV-out cable will have to sit near the PS3 looking, at the PSP screen from a distance with Dual Shock 3 in hand. It's a neat experiment, to be sure, but doesn't seem to be an entirely compelling feature. Be sure to watch out for hands on impressions of PSP Plus following the launch of Resistance: Retribution.
